The Atacama Large Millimeter/submillimeter Array, an international telescope project, reached a major milestone on March 2, when two ALMA prototype antennas were first linked together as an integrated system to observe an astronomical object.

Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc, the nonprofit research corporation that operates the National Radio Astronomy Observatory.

Astronomers have discovered the strongest evidence yet found indicating that matter is being ejected by a medium-sized black hole, providing valuable insight on a process that may have been key to the development of larger black holes in the early Universe.

New, high-precision distance measurements by the National Science Foundation’s Very Long Baseline Array (VLBA) radio telescope are providing a major advance for astronomers trying to understand how stars form.

Astronomers have used the National Science Foundation’s Very Large Array radio telescope to image a young, multiple-star system with unprecedented detail, yielding important clues about how such systems are formed.

The National Science Foundation’s Astronomy Senior Review Committee report, released today, made major recommendations for restructuring the NSF’s ground-based astronomy efforts, including significant changes for the National Radio Astronomy Observatory.
